Scope note
Complex pure substances made up of two or more elements in definite proportions with respect to the number and kind of atoms, held together by chemical bonds. They have entirely different properties from those of the constituent elements, which lose their individual character. For combinations of two or more substances in no definite proportions that are only physically mixed and within which the constituent substances retain their individual properties and are separable by ordinary physical means, use "mixtures."
